Be it known thatI, FELIX A. OARNEY,

citizen of the United States, residing at.

Memphis, in the county of Shelby and State of Tennessee, haveinventednew and useful Improvements in Handle-Turning Machines,

of which the following is a specification.

This inventionrelates to improvements in wood working machines and moreparticularly to a machine forturningthe ends of tools, brooms, mops, orother handles.

It is the object of this invention to provide a machine to which may befed the handles as they come from the lathe and from which the handlesare discharged with the end completely turned. l I

' The advantages ofsuch aemachine are obvious as themachme Worksautomatlcally.

The construction is extremely simply and does away with all manualhandling of the articles as a step by step conveyer successivelyadvances each handle toward the cutter, a positive gripping meansholdsthe handle opposite the cutter which is ad-- vanced against the roughendof. thevhandle and withdrawn automatically: from the. turned end Iand: the finished handle dis; charged.

'W'hile thepreferred forms of this invention are illustrated upon theaccompanying drawings, yet-fit is to. be understood that minor detailchanges maybe made without departing from the scope thereof."

Figure 1 isa view-in sideelevation of a complete machine constructed" inaccordance with thisinvention." Fig.2 is'a top plan view of the same.Fig. "3 is a. transverse sectional view taken on the line 3"3 of Fig.

1 looking in the direction of the arrow. Fig. 4 is a similar viewtakenon the line 4 .l looking in the direction of the arrow. Fig. 5 is afragmentary view. in elevation of one end of themachine. Fig. 6 is a-par-' tial' longitudinal vertical sectional view taken on the line 66of Fig.2.

The handles as they come from the lathe are manually fed end to'end intothe guide 1 extending across the front of the machine. The machine sideof the guideiis provided with guards 2 adjustable, "accordance with thelength of thehandles to'be turned, to retain the handles passing throughthe guide until the fartherend reached when.

the handle is discharged bygravity upon. a step 'by step conveyer. qThisconveyer 1sarranged transversely of the frame of the machine andcomprises a plurality of fixednotched members 3 extending from below theguide upward at an angle with the bottom of onenotch inline with thecutter. On the adjacent sides of each-pair of fixed members '3' arearranged similar movable members lv the upper and lower ends ofeach pairof the movable members being con nected by a'rbrace 5 having a centraldependmg arm 6.; Operating shafts? are mounted 1n bearings upon theunder side'of the fixed members at top and bottom which shafts areprovided with a; sprocket and a crank arm 8 plvotally connected to the,arm 6 so that.

when the shafts'are rotated in the samefdirection an oscillatingmovementis imparted to, the members 4- and a handle, shown in dotted lines onFig. :8, restingv upon the notches of the fixed member will be engagedandadvanced upward one notch upon each oscillation of the movablemembers.

g Between the far end of the machine frame and adjacent the contiguousfixed member 3- 0f the conveyer a transverse guide in the form of aplate 9.is mounted upon a transversesupport and this transverse guidewill be engaged by the end of the handle to be finished upon'itsdischarge from the longi+ tudinalguidexl so; that upon its upwardtravelupon the conveyer each handle will occupy the isamerelativeposition when it reaches the center notch of thefixed member.

Opposite this center notch a cutter head 10 is carried upon, alongitudinal shaft 11' mounted to .both rotate and travel longitudinallyin bearings upon the end-of the machine fram'e'and transverse support.This shaft is provided with a fly wheel 12 and a belt pulley'13 adaptedto be connected to a powerv shaft by belt. .As eachhandle is loweredinto the center'fixed notch it passes between two jaw heads 14rotatably-mounted upon the ends of two jaw. arms 15 which grip and holdthe handle while the cutter head advances and 'turnsthe end. Upon thewith drawal of the cutter head the jaws open and release the finishedhandle which is advanced a step up the conveyer a "new-handle placedbetween the jaws. s I

r The cutter head 10 .is advanced andwithdrawn and the gripping j awsMare operated from a longitudinal driven shaft 16 cen trallymounted inbearings upon the lower portions of'the machine frame. A driving shaft.17 parallel to the driven shaft is mounted: to. one side thereof inbearings upon the farther end of the frame and transverse support with abelt pulley 18 upon the end extending beyond the end of the frame. Thedriving shaft 17 is provided with a pinion 19 meshing with a gear wheel20 upon the driven shaft and the driving shaft is preferably driven inthe reverse direction from the cutter shaft 11 by a twisted belt from apower shaft 21, the gear and pinion connection between the driven anddriving shafts reducing the speed of the driven shaft.

The cutter shaft 11 is reciprocated by means of a cam 22 upon the drivenshaft 16 between the conveyer and transverse support engaging one end ofa bell crank lever pivotally mounted at its apex upon a transverse'pin23 and having its other end forked to engage a sleeve 24 therefor uponthe cutter shaft between its belt pulley and fly wheel. The cam 22 ispreferably in the form of a circle with a cutoff flat 25 which willallow the cutter head to be advanced to engage the end of the handle andcompletely turn the end before it is withdrawn by the rotation of thecam, the circular portion maintaining the cutter head in the retractedposition until the finished handle has been removed and a new onesubstituted. The lower end of the bell crank lever is provided with aroller :26 traveling about the cam and is held in contact therewith bymeans of an arm .17 pivoted at one end to the upper portion of thetransverse support through which this arm of the lever freely passes andhaving a weight, or other means, to hold the roller on the cam.

In order to regulate and adjust the amount of advance of the cutter head10 the bell crank lever is preferably constructed in two parts, thelower arm 28 being pivoted to the transverse pin 23 and provided with aflat upper surface thereover while the lower end of the upper arm 29 isbranched to straddle the lower arm and the ends pivoted to thetransverse pin. Between the branches the upper arm is provided with aprojection 30 on each side parallel to and overlying the flat surface ofthe lower arm. The angular relation of the two arms may be adjusted andheld by set screws 31 engaging the projections and flatsurface on eitherside of the pivot pin. p

The gripping jaws 14 are also operated through a cam 32 upon the drivenshaft 16 mounted intermediate the ends of the conveyer. The aw arms 15are in the form of oppositely extending bell crank levers, pivoted attheir apexes by longitudinal pins in a transverse support between thefixed conveyer members adjacent the chuck end. The upper ends carry thepivoted horizontal jaw heads 14: and the lower ends are connected bypivoted pins 33 to a sleeve 3ft about the end of a floating longitudinalshaft 35. The opposite end of the floating'shaft is mounta roller 37 ismounted which rides upon the cam 32 upon the driven shaft. This cam ispreferably in the form of an eccentric so shaped that as the cutter headadvances the end sleeve 34 on the floating shaft will rise up upon thejaw arms 15 so that the aw heads will grip the handle and hold it untilthe end is turned and upon the withdrawal of the cutter head the jawheads will open.

A sprocket 38 is provided upon the driven shaft in line with thesprockets on the longitudinal. conveyer shafts which are driven in'thesame direction by a chain passing over them. The upper ends of the fixedmembers of the conveyor are provided with an incline 39 to discharge thefinished handles into a proper receptacle. 7
